y shown, by broken lines, in one of the posithe base 10 as explained, the stein 1Q of the tions to which it maybe shifted relative to the glide 1S lSSemblcd therewith. This stem is base, y f i similar to the one commonly employed with Figure 3 is applan view of the top disk of furniture casters but its lower endis formed with a rounded foot 13 the diameter of `which 5.

Figure 4 is a side elevation thereof.` is greater than the diameter of the opening 2; Figure 5 is a top plan view of the bottom The opposed concaved portions of the disks disk of the connecting structure. 1 and 6 cooperate to retain this foot therem Y Figure 6 is a side elevation thereof. between but the opening Qis of such size as 100 Figure 7 is a top plan vievs1 of a modifiedl to permit the stem 121Go oscillate in any direc* tion, the bottom surface of the foot at'all times pressing downwardly against the disk 6 which thus serves to receive wear and to protect the base 1Q.

By having the two disks interiit as shown, the material of which the base 10 is formed will not press between the disks while being molded therearound. Instead the space between the concaved surfaces of the disks will be kept clear so that no obstructions will be formed therein which might interfere with the sliding movement of the foot 13 between the disks.

As the lower disk 6 receives the thrust from the stem 'l2 and its foot 13, the strain will be distributed over an extensive part of the base so that the danger of breaking or cracking said base is `practically eliminated.

The prima'y advantage in having a glide such as described is that, when ,it is substituted for an ordinary furniture caster, the base 10 will remain flat on the supporting surface even though the article of furniture may be tilted. The base will also adapt itself to an inclined supporting surface. Consequently the danger of breaking the base because of an unequal application ofv pressure therethrough to the supporting surface or because of the positioning of the base with its contact point remote from the center is entire'ly avoided. Furthermore the movable connection between the base and the stem permits the base to rock while passing over an obstruction in the path thereof.

Y Instead of fo ming the upper disk with depressions 5 as illustrated, the same may be provided with downstruck ears 14 at the margin thereof which will project into the molded base and hold the disk against rotation. This has been kclearly illustrated in Figures 7 and 8.

rIwo very'importa-nt features of the present invention are, first, the molding of the glide aroundv the disks so that when the materia-l of the base hardens, the disks will be firmly assembled therewith; and second, the provision of disks which tightly interfit so that when the material of the base is molded under pressure no part thereof will exude into the cavity between the disks.

That is claimed is:

1. A glide including interfitting concavoconvex disks oppositely disposed to provide a. space therebetween, there being an aperture in one of the disks, a one-piece base in which the marginal portions of the disks are embedded, said base constituting means for holdingr the disks against separation a stem iaving one end movably mounted between the disks, said stem being mounted to swing in any direction within the opening, and means on the stem and cooperating with one of the disks for holding the stem against separation from the base and disk.

2. A glide for furniture and the like including interfitting superposed disks providing ay space therebetween, the disks being in contact adjacent their margins a base in which the marginal portions of the disks are embedded, said base constituting means for holding the marginal portions of the disks in Contact andagainst separation from the base, `said base also' providing a backing for all portions of the lower or inner disk, there being an opening in the other disk, a stem having one end seated between the disks, said stem mounted to swing in any direction within the opening, means on the lower end of the stem cooperating with the disks to hold the stem against withdrawal from engagement with the disks, the lower disk constituting means for transmitting thrust from the stem to an extensive area of the base.

3. A glide for furniture and the like including interlitting superposed disks contacting adjacent their margins but providing a space between the central portions of the disks, a base in which the marginal portions of the disks are embedded, said base constituting means for holding the marginal portions of the disks in contact and against separation from the base, said base also providing a backing for all portions of the lower or inner disk, there being an opening in the other disks, a stem having one end seated between the disks, said stem mounted to swing in any direction within the opening, means on the lower end of the stem cooperating with the disks to hold the stem against withdrawal from engagement with the disks, the lower disk constituting means for transmitting thrust from the stem to an extensive area of the base, and means on one of the disks embedded in the base for holding the disks against rotation in the base.

4. A glide for furniture andthe like including interlitti'ng members contacting at their margins and providing a cavity between the middle portionsfof the members, and a base in which the marginal portions of the members are embedded, said base constituting means for holding said members in contact and against separation from thebase.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
